Multifilament yarn, monofilament, or film-type structure at least substantially of polyethylene naphthalate, with a strength of, at least 400 mN/tex, characterized in that it has a DSC melting point of at least 292°C, whereby the DSC melting point is measured on a sample quantity of 2.5 mg at a heating rate of 20°C per min. It consists preferably of at least 95% by weight polyethylene-2,6-naphthalate. For production, melted polyethylene naphthalate is extruded from a multi-hole spinneret, the filaments or film, solidified by cooling, are/is withdrawn at a rate of 500 to 000 m/min, whereby the filaments or film are/is subjected to a draw-down B of 40 to 25 000 from the spinneret output to the first withdrawal element. The polymer used contains at least 85% by weight polyethylene naphthalate and has a melt flow index C of 3 to 26.
